Default Post your Linpack max temps

I'm curious what sort of temps people are seeing during Linpack stability testing.
Could you post you max temp in the following format:
  • Temp
  • Processor
  • OC freq
  • voltage
  • Whether Load line calibration was used for voltage
  • case, if relevant
  • cpu cooler

You can download OCCT here, use the Linpack test and crank your fans.

Link to developers site: Download - OCCT Website english

Link to Console version of a Linpack tool, this one seems to produce a little higher temps, and does not have a shutdown at 80C:
IntelBurnTest v2.3 download from Guru3D.com

Real Temp is useful for giving as accurate temps as possible:
Real Temp - CPU temperature monitoring
(45nm processors do not provide accurate temp feedback at idle, as the sensors are only tuned to be accurate at TJmax)

If you use this there is no high temp limit other than your cpu throttle:

Temps shown on OCCT while running at its maximum test phases observed are 62-64

Keep in mind thats under its full LinPak load possible test condition

And a 3hr test also displayed same parameters.
